Несмотря на классическое представление о стабильном ЭКГ-паттерне типа 1, известно, что у некоторых пациентов наблюдаются транзиторные проявления, что создает дополнительные сложности в диагностике и выборе тактики лечения. В статье представлен клинический случай транзиторного синдрома Бругада, рассмотрена последовательность обследования при подозрении на данную патологию. Изучение данного феномена является актуальной проблемой, поскольку динамическая изменчивость ЭКГ-проявлений и стертая клиническая картина затрудняют своевременную диагностику, что увеличивает риск внезапных жизнеугрожающих аритмий.</p></abstract><trans-abstract xml:lang="en"><p>Brugada syndrome is an inherited channelopathy characterized by specific electrocardiographic (ECG) abnormalities, an increased risk of life-threatening ventricular arrhythmias, and sudden cardiac death. Despite the classical presentation of a stable type 1 ECG pattern, it is known that some patients exhibit transient manifestations, which complicates diagnosis and treatment strategy selection. This article presents a clinical case of transient Brugada syndrome and discusses the diagnostic approach when this pathology is suspected. The study of this phenomenon is highly relevant, as the dynamic variability of ECG findings and the often-subtle clinical presentation hinder timely diagnosis, thereby increasing the risk of sudden, potentially fatal arrhythmias.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Бругада</kwd><kwd>ЭКГ</kwd><kwd>сердечно-сосудистый риск</kwd><kwd>наследственные каналопатии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Brugada syndrome</kwd><kwd>ECG</kwd><kwd>cardiovascular risk</kwd><kwd>hereditary channelopathies</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Antzelevitch C., Patocskai B.
